A New Method for Emission Control System Malfunction Detection During the Periodic Technical Inspection
(Corresponding) Rešetar M., Pejić G., Ilinčić P., Lulić Z.
Topic:
Gas emissions control and utilization
The paper shows a new method for detecting emission control system malfunction during periodic technical inspection (PTI). The on-board diagnostic (OBD) test results were collected and processed during the PTI of vehicles in Croatia in 2020. The study included petrol and diesel passenger cars that...Read more
What is the impact of earth observation and in-situ data assimilation on seasonal hydrological predictions?
(Corresponding) Pechlivanidis I., Musuuza J.
Topic:
Process understanding through innovative sensors and remote sensing
Earth Observations (EO) have become popular in hydrology because they provide information in locations where direct measurements are either unavailable or prohibitively expensive to make. Recent scientific advances have enabled the assimilation of EOs into hydrological models to improve the...Read more

Influence of the addition of M2+ (M: Co, Cu, Zn) on the properties and activity of W-TiO2 and Mo-TiO2 photocatalysts for water remediation
Mergenbayeva S., (Corresponding) Poulopoulos S., Grilla E., Vakros J., Mantzavinos D.
Topic:
Advanced oxidation processes
In this study, ternary systems of M1M2TiO2 (M1:Co, Cu, Zn) M2 (WO3, MoO3) were prepared and tested for the photocatalytic degradation of sulfamethoxazole. It was found that W-oxo species can be used without significant alteration of the TiO2 activity, while only Cu is a possible candidate for the...Read more
Large sample hydrology and its importance in hydrological forecasting
(Corresponding) Pechlivanidis I., Crochemore L., Girons Lopez M.
Topic:
Hydrology and water resources
Catchment scale investigations are indeed valuable for detailed process investigation and therefore to understand the local conditions that affect forecast skill. However these are limited when it comes to scaling up the underlying hydrometeorological hypotheses. To advance knowledge on the drivers...Read more

Penetration of tritium into ground water in the Czech Republic
(Corresponding) Juranová E., Sedlářová B., Marešová D., Pohlová I.
Topic:
Environmental data analysis and modelling
Tritium (3H), the radioactive hydrogen, can form naturally by interaction of the cosmic radiation with the atmosphere, or it can be produced by human activities. In recent, tritium occurs distributed in environment in low concentrations, which means no significant health risk, but it can be used...Read more
The potential impact of an implementation of microalgae-based wastewater treatment on the energy balance of a municipal WWTP in Central Europe
(Corresponding) Hasport N., Krahe D., Kuchendorf C., Theilen U., Beier S.
Topic:
Environmental biotechnology and bioenergy
The integration of a photobioreactor for wastewater treatment by microalgae is proposed as a future alternative for cost-efficient and environmentally friendly nitrogen and phosphorous removal in municipal WWTPs. The high growth rates and higher biogas yields (compared to conventional sewage sludge...Read more

Alternative wastewater treatment process with algae (AlgA) – general mathematical model and dynamic simulation
(Corresponding) Lorenz T., Behr A., Theilen U.
Topic:
Wastewater treatment
Conventional wastewater treatment systems are based on processes including the steps of pre-/ primary, sec-ondary and finally the sludge treatment. In this study a treatment step with algae as an alternative secondary treatment is supposed to improve the biological nutri-ent removal efficiency.
In...Read more

Photocatalytic Removal of Pesticides Present in Agro-industrial Water Effluents
Arfanis M., Theodorakopoulos G., Anagnostopoulos C., Georgaki I., Liappis K., Romanos G., Markellou E., (Corresponding) Falaras P.
Topic:
Wastewater treatment
Pesticide residues accumulated in agricultural wastewaters constitute a potential risk for the environment and the human health. Hence, focused actions for their elimination are of high priority for both the industry and national authorities. This work evaluates the effectiveness of the...Read more
Determination of atmospheric amines in boreal forest using unmanned aerial drone with an integrated miniaturized air sampling system
Pusfitasari E., Ruiz-Jimenez J., Heiskanen I., Jussila M., Hartonen K., (Corresponding) Riekkola M.
Topic:
Atmospheric chemistry and physics
Amines are ubiquitous in the atmosphere and their presence is considered important especially due to their hazard to human health and their contribution to new particle formation that can affect climate change. In this study, tailor-made mesoporous functionalized silica sorbents were used in in-...Read more
Removal of wood dyes from aqueous solutions by sorption on un-treated pine sawdust
Pimentel C., Freire S., Gómez-Díaz D., (Corresponding) González-Álvarez J.
Topic:
Wastewater treatment
Synthetic dyes are extensively used in industry for various applications among which is the preparation of dyed wood veneers. The discharge of effluents containing dyes is of great concern due to their toxicity, mutagenicity and carcinogenicity and causes serious environmental problems. In this...Read more
